Application filed August 29, 1314. Serial Ho. 858,159.

To (ZZZ urlmm it may concern Be it known that I, AMOS Asonnws, a citizen of the United States, and a resident of Plainliel'd, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Irrigatlng Plants, of which the following is a specification.

This invention relates to irrigation systems and particularly to a system utilizing motors of the reciprocating piston type.

The invention contemplates the provision of an irrigating plant comprising reciprocating motor for moving or oscillating in unison a plurality of spraying members.

The main object of the invention is to provide a system of a simple construction inexpensive to manufacture and which operates with great efficiency at the expense of a small amount of energy.

With these and other objects in view the invention preferably comprises a plurality of horizontal perforated pipes supported by a suitable means permitting the oscillation of the pipes. These pipes receive Water from any desired source, and are so connected to a reciprocating Water-motor that the movement of the motor piston rotates the pipes. Certain features of the motor cooperate with these elements to produce vari ous advantageous results.

Other features of the invention will appear as the specification proceeds.

The drawings accompanying the speoifica tion illustrate the invention in a concret and preferred form but it to be understood that the inventiouis capable of many changes and modifications withoutdeparting from the spirit and scope of the invention as is set forth in the appending claims.

In the drawings: Figure 1 is a side elevation of the motor showing the same con= nected with a plurality of spraying mems. Fig. 2 is a fragmcntal detail view of t three-Way valve which controls the iiovv raid pressure to the cylinder and partly shown in section to illustrate the detail con struction thereof. 3 is a vertical sectional view substantially at right angles to Fig. l and taken on the line of Fig. i. Fig. l is a view similar to Fig. 3, sh ,v:rng more or less diagrammatically the genera arrangement of motor, spraying men 1 and suppogts footheiatter.

similafreterence characters resisting means lar parts throughout the specification and drawings. j

1 denotes a cylinder, preferably supported in 2.. vertical position in any desire-ole manner upon the base 2, although the cylinder is here shown as threaded in the base so that the same may be easily and quickly dismantled for the purpose of cleaning, etc. A piston 3 is adapted to reciprocate in thecylinder and has the piston rod at preferab" extending through the upper end of the inder l. The cylinder is provided upper end with the removable cap having a suitable stufiin'g means through Which the rod l extends.

A pipe connection 7 conc rts the cylinder 1' With a main supply 8 through the branch connections 9 and 10, which latter is so connected to the cylinder to in roduce fluid pressure from supply pipe 8 to opposite sides of the piston 3. Preferably in actual use only one of these branch connections 9 and 10 is brought into use during the operation of the motor, since fluid pressure is in the present instance used to efiect the stroke of the piston in one direction only.

However, by the connections 9 and 10 the direction of movement of the fluid pressure stroke may he changed at will by the manipulation of either of the cut-ofi' val .1 or 1:2.

in the p red embodiment, herein shown, m valve is normally normally open, and n any suitahle winder through 1e Water under p source is supplied the pipe 8, pipe 7 upon the upper side 0 the same downward.

no piston 3 to force iy siutaole pressure toe form here dist ic piston for torciu the cylinder 1 of operan the present is connected e or closed be connected ing the same and thereby tion of the zi i 4 instance a countcrweig with the piston rod 1 W chain Ll which passes on pulleys and 1G suitably supported :2 lane the otor the supp "ts 17. This counterwei 73 operates t. ect the return stroke of the piston when haust to the cylinder 1 is open, thus allr ,ng the Water pressure,'vvhich has been acting upon the piston, to escape therefrom under the tension or stress of the counter "lit The supply of Water under pressure to the cylinder for operating the piston 3 is auto motically governed by the three-way valve 18 which will establish communication between the'main supply pipe 8 and the pipe connection 7 and between thepipe connec- The rod 2d has the collars 26 and 2? adjustable'thereon-and adapted'to be engaged by the arm 28 adjustably secured upon the piston rod 4. As the piston rises end'falls the arm 28 engages with the collars and reciprocstes the rod 24: upwardly and downwardly with the piston ,3.

The race 20'is connected withan operatmg lever 29 of the three-way valve '18 by the slotted linlr 30 which is pivotaliy secured to the race.

Now assuming that-the arts above described are in the position s own in Fig. 1,

water pressure will enter through pipe 8 and branch connection 9 to the cylinder and will move the piston downwardly. The collar 28 v is so hdjusted upon the rod 24 that when the piston is about to flush its downward-stroke the arm 28 will engage the collar 26 and move the rod 2i downwardly, with the piston, and therod 2 will, in turn swing the race 2-0 upon its axis from the position shown in dotted lines, Fig. 1, to a position where the end 2G thereof will be tilted slightly below the horizontal axis of the race. During this'r'novement of the race,

the lever connections between the same and the valve 18 will not operate the latter to any extent to cut off the fluid pressure to the cylinder 1,: but as soon as the end 20 of race is tilted below its horizontal axis the ball 23 will roll from the end 20 to the end 20 and thus efiect a sudden drop of the end 20 to the bumper 31, which will rotate the valve 18 quickly and positively to shut oil fluid pressure to the cylinder and will 7 open the cylinder to the exhaust 19. Now that the pressure in the cylinder 1 is open to the atmosphere the pressure resisting means 13 will gradually raise the piston and force the water in the cylinder through the branch pipe 9 and. out through the exhaust l9, and thereby return the piston to its normal or-initial position. Now as the piston is about to finishits upward or return stroke the arm 28 will engage with the collar 2'? on the rod 2% and will slowly raise the end 20 of the race 20 from the position shown in full lines, Fig. 1, to a tilted position slightly The rapidity at which each stroke of the piston will operate depends upon the rapidity at which the fiuid pressure is supplied to and-exhausted from the'cylinder, which maybe controlled, and in the present'instance is, by the valve 18. B the bumpers 31 and 32 and there y limitingthe final or quick movement of the race 20 the position of the valve 18 may be regulatedand the rapidity of operation of the piston varied. In the event it is desired to efi'ect a adjusting slow movement of one stroke of the piston and a quick movement of the return stroke of the piston, the bumpers 31 and 32 may be independently adjusted for varying the operation .of. the valve 18. The irrigation is effected through a plurality of horizontal perforated pipes 33 supported by any suit-. able means 34 which will allow the pipes to rotate upon their axes. 'These pipes re' ceive water from any desired source and have one end secured to the cable 14: so that upon each stroke of the piston these spraying pipes 33 may be oscillated or swung about their axes, as may be clearly seen from Figs. 1 and 3. A cut-off valve -35 is pro vided in. the'miiin supply pipe 8 for cutting oil fluid pressure to the cylinder 2.
